Deploy stops at just over a hundred MB

We have been using FOG for some time now and have recently experienced a problem where image deployment is hanging, or at least slowing down to an extremely slow rate.

Uploading images is fine. I have changed the network hardware, attempted to deploy a new image as well as one known to be working previously and also attempted to deploy to different hardware. I have also attempted to upgrade and downgrade the kernel.

I have recorded the problem on a video (I am sorry it is a little shakey!) and made it available on youtube - I hope this is within the rules. The problem can be seen here:

I am actually experiancing this same problem at another Site… Slightly Different, I am trying to Deploy Windows 7 on Hardware that I have imaged before… It Processes the First Partition as normal, Starts Partition #2 and Literally stops at 65.20 MB or at 2-4 seconds…

I havent touched my fog server in about a month but I used it to Multicast all my labs. now im trying to Unicast my Classrooms and the same as above happens…

Ive changed Patch Coords/Switch Port and also reset the switches… Anyone else have a fix for this?
